Discover Lake Natron
A lake of salt, fire and flamingos.
Lake Natron is a salt and soda lake in the Arusha Region of northern Tanzania, lying close to the Kenyan border in the Gregory Rift, the eastern branch of the East African Rift. Set at an elevation of about 600 metres, the lake measures some 57 km long and 22 km wide, with a total surface area of around 1,040 km². It is remarkably shallow, less than 3 metres deep, and its width varies with the water level from season to season.
The lake is fed principally by the Southern Ewaso Ng'iro River, which rises in central Kenya, and by mineral-rich hot springs. Air temperatures here are frequently above 40°C (104°F), while the hot springs and shallow pools can reach around 60°C (140°F). Together with its high and variable salt content, this makes the lake inhospitable to most animals. Irregular seasonal rain falls between December and May, totalling around 800 mm a year, and high levels of evaporation leave behind crusts of natron (sodium carbonate decahydrate) and trona (sodium sesquicarbonate dihydrate).
As the water evaporates during the dry season, salinity climbs to the point where salt-loving micro-organisms begin to thrive. Cyanobacteria make their own food by photosynthesis, just as plants do, and the red accessory pigment they contain produces the deep reds of the open water and the vivid oranges of the shallows, colours that make Natron one of the most surreal landscapes in Africa.
Why Lake Natron
Raw Rift Valley wilderness, far from the crowds.
Lake Natron rewards travellers who want something wilder than the classic circuit: volcanic scenery, extraordinary birdlife, Maasai culture and a genuine sense of remoteness.
Ol Doinyo Lengai
The Maasai 'Mountain of God' rises above the southern shore. It is the only active volcano on Earth known to erupt natrocarbonatite lava, and Natron is the base for climbing it.
Otherworldly Colours
Red and orange waters, white salt crusts and black volcanic rock create a landscape that looks almost unearthly, especially from the air or at sunrise.
Waterfall Gorge Walks
A short hike up the Engare Sero gorge leads to a lush waterfall and natural pools, a welcome contrast to the heat of the lakeshore.
Maasai Country
The area is home to Maasai communities who graze cattle across the plains, and village walks offer an authentic insight into pastoral life.
Ancient Footprints
Near Engare Sero, hundreds of human footprints preserved in volcanic mud thousands of years ago offer a rare window into the region's deep past.
Location
Where is Lake Natron?
Lake Natron lies in the far north of Arusha Region, close to the Kenyan border. From Arusha, the usual route heads west to Mto wa Mbu and then north along the floor of the Rift Valley past the ancient ruins of Engaruka, a journey of roughly 240 km that takes about 4 to 5 hours, with the final stretch on rough, dusty tracks. Kilimanjaro International Airport is about an hour further east of Arusha.
The main base for visitors is the small settlement of Engaresero (Ngare Sero) near the southern shore, where campsites and tented camps sit between the lake and the escarpment. Natron can be combined with Lake Manyara and Ngorongoro, or used as a back-door route to the northern Serengeti through Loliondo. Scenic and charter flights also serve the area for those short on time.
When to visit
How the seasons shape Lake Natron.
Natron is hot and dry for much of the year. The seasons change the lake's colours, its water level and the activity of the flamingos.
Dry Season
The most comfortable time to visit, with clearer skies, cooler nights and good conditions for climbing Ol Doinyo Lengai. Evaporation intensifies the lake's red and orange hues.
Flamingo Breeding
Lesser flamingos typically gather to breed on the remote mudflats as the lake shrinks, although timing depends on rainfall and water levels each year.
Rainy Season
Irregular rains, totalling around 800 mm a year, refresh the plains and raise the lake. Some tracks become difficult, but the landscape turns green and visitors are few.
Hot Interlude
A drier spell between the rains, often very hot by day, with large numbers of flamingos still feeding on the lake.
What is the best month to visit Lake Natron?
June to December is the most popular period, but Natron's raw beauty can be enjoyed all year with the right planning.
Very hot by day, with flamingos often feeding in large numbers on the lake.
A short dry spell between the rains, good for photography in the early morning light.
Rains become more frequent and some access tracks can turn muddy.

Flamingo numbers build as the water level drops and breeding activity often begins.
Great walking weather, with vivid lake colours and good flamingo viewing.
Hot and dry, often a strong month for flamingo breeding on the distant mudflats.
The short rains approach, though Natron's dry climate often keeps conditions good.
Short rains refresh the land, and young flamingos may still be seen on the lake.
Explore the area
Explore the shores and surroundings of Lake Natron.
Most visits centre on the southern end of the lake, where volcanic peaks, rivers and Maasai villages meet the salt flats.

Wildlife
Life at the edge of the possible.
The heat, salt and alkalinity of Lake Natron make it inhospitable to most animals, yet the lake supports one of the great wildlife spectacles of Africa. Lesser flamingos feed on the cyanobacteria that colour the water, and the caustic, predator-free mudflats make the perfect nursery. This lake is the only regular breeding area in East Africa for around 2.5 million lesser flamingos, whose near-threatened status reflects their dependence on this single site.
Around the lake, a variety of species thrive and stroll along the shore and plains. Plains game such as zebra, wildebeest and gazelles graze the Maasai grasslands, while dry-country specialists and a rich community of waterbirds and raptors make Natron a rewarding stop for birders.

The Flamingo Breeding Grounds
Where millions of flamingos begin life.
Every year, vast numbers of lesser flamingos gather on Lake Natron to breed. They build mud-mound nests on islands of salt deep in the lake, where the caustic water keeps predators away. Around 75% of the world's lesser flamingos are born here, making Natron the single most important breeding site for the species.
Walking quietly across the mudflats near Engaresero, you can watch flocks feeding in the shallows, their pink plumage glowing against the red water and the dark cone of Ol Doinyo Lengai. It is one of the most remarkable wildlife sights in East Africa.

The story behind Lake Natron.
For centuries, the Natron basin has been Maasai land. Pastoralists graze their cattle across the plains and revere Ol Doinyo Lengai as the home of Engai, their god. Nearby, the Engaruka ruins tell of an older farming community that built stone terraces and irrigation channels along the escarpment, while fossil finds at Peninj, west of the lake, and the human footprints at Engare Sero show how long people have walked this part of the Rift Valley.
Today the lake is recognised as a wetland of international importance under the Ramsar Convention, largely because of its role as the flamingos' nursery. Its fragile chemistry and dependence on inflowing rivers mean conservation is vital: proposals for industrial soda ash extraction and changes to water flows upstream have been strongly opposed by conservationists, and community-based tourism now helps local Maasai benefit from protecting the lake.
Is Lake Natron worth visiting?
Yes, for travellers who love dramatic scenery and adventure. The flamingos, the red lake, Ol Doinyo Lengai, the waterfall gorge and Maasai culture make it one of Tanzania's most memorable off-the-beaten-track destinations.
When can I see flamingos at Lake Natron?
Flamingos are present for much of the year, with the largest numbers and breeding activity usually from around August to December. Exact timing depends on rainfall and water levels.
Can you swim in Lake Natron?
No. The water is highly alkaline and very hot in places, and can burn skin and eyes. Swimming is instead enjoyed in the freshwater pools of the Engare Sero waterfall.
How far is Lake Natron from Arusha?
Roughly 240 km, about 4 to 5 hours by road via Mto wa Mbu. The last section is on rough tracks, so a 4x4 vehicle is essential.
How hard is the Ol Doinyo Lengai climb?
It is a steep and demanding climb on loose ash, usually started around midnight to reach the crater rim at sunrise. Good fitness is needed and an experienced local guide is required.
How many days should I spend at Lake Natron?
Two nights is ideal, allowing time for the flamingos, the waterfall gorge and either the footprints or a climb of Ol Doinyo Lengai.
Can Lake Natron be combined with the Serengeti?
Yes. Natron can be reached from Lake Manyara and Ngorongoro, and a route north through Loliondo leads to the northern Serengeti for a true adventure safari.
